Top 5 Biotech Companies To Invest In Right Now: Inovio Pharmaceuticals Inc (INO)

Inovio Pharmaceuticals, Inc., incorporated on June 29, 1983, is engaged in the development of a new generation of vaccines, called synthetic vaccines, focused on cancers and infectious diseases. The Company's SynCon technology enables the design of universal vaccines capable of providing cross-protection against existing or changing strains of pathogens, such as influenza and human immunodeficiency virus (HIV). The Company's electroporation delivery technology uses brief, controlled electrical pulses to increase cellular uptake of the vaccine. Its clinical programs include cervical dysplasia (therapeutic), avian influenza (preventive), prostate cancer (therapeutic), leukemia (therapeutic), hepatitis C virus (HCV) and HIV vaccines. It is advancing preclinical research and clinical development for a universal seasonal/pandemic influenza vaccine, as well as preclinical work for other products, including malaria and prostate cancer vaccines. Its partners and collaborators include University of Pennsylvania, Drexel University, National Microbiology Laboratory of the Public Health Agency of Canada, Program for Appropriate Technology in Health/Malaria Vaccine Initiative (PATH/MVI), National Institute of Allergy and Infectious Diseases (NIAID), Merck, ChronTech, University of Southampton, United States Military HIV Research Program (USMHRP), the United States Army Medical Research Institute of Infectious Diseases (USAMRIID) and HIV Vaccines Trial Network (HVTN). As of December 31, 2011 it owned 16.1% interest in VGX Int��.

Inovio�� Solution

The Company�� synthetic vaccine platform consists of its SynCon vaccine design process and electroporation delivery technology. It has developed a preclinical and clinical stage pipeline of vaccines. The Company�� synthetic vaccines are designed to prevent a disease (prophylactic vaccines) or treat an existing disease (therapeutic vaccines). Its synthetic vaccine consists of a deoxyribonucleic acid (DNA) plasmid encoding a selected antigen! (s), which is introduced into cells of humans or animals with the purpose of evoking an immune response to the encoded antigen. The Company�� synthetic vaccines are designed to generate specific antibody and/or T-cell responses.

The Company�� SynCon technology provides processes that employ bioinformatics, which combine extensive genetic data and sophisticated algorithms. Its design process uses the genetic make-up of a common antigen(s) from multiple strains of a virus within a viral sub-type or taxonomic group (family) of pathogens, such as HIV, hepatitis C virus (HCV), human papillomavirus (HPV), influenza and other diseases to synthetically create a new antigen for the desired pathogen target that does not exist in nature. Its synthetic vaccine candidates are being delivered into cells of the body using its electroporation (EP) DNA delivery technology.

Cancer Synthetic Vaccines

The Company has two broad types of cancer vaccines: preventive (or prophylactic) vaccines, which are intended to prevent cancer from developing in healthy people, and treatment (or therapeutic) vaccines, which are intended to treat an existing cancer by strengthening the body�� natural defenses against the cancer. Two types of cancer preventive vaccines are available in the United States. The United States Food and Drug Administration (the FDA) has approved two vaccines, Gardasil and Cervarix that protect against infection by the two types of HPV-types 16 and 18-that cause approximately 70% of all cases of cervical cancer worldwide. In addition, Gardasil protects against infection by two additional HPV types, 6 and 11, which are responsible for about 90% of all cases of genital warts in males and females but do not cause cervical cancer.

Cervarix manufactured by GlaxoSmithKline, is composed of virus-like particles (VLPs) made with proteins from HPV types 16 and 18. Cervarix is approved for use in females��ages 10 to 25 for the prevention of cervical cancer caused by! HPV type! s 16 and 18. Gardasil manufactured by Merck, is approved for use in females for the prevention of cervical cancer, and some vulvar and vaginal cancers, caused by HPV types 16 and 18 and for use in males and females for the prevention of genital warts caused by HPV types 6 and 11. The vaccine is approved for these uses in females and males ages 9 to 26. The FDA has also approved a cancer preventive vaccine that protects against hepatitis B virus (HBV) infection.

Inovio�� VGX-3100 is designed to raise immune responses against the E6 and E7 genes of HPV types 16 and 18 that are present in both pre-cancerous and cancerous cells transformed by these HPV types. E6 and E7 are oncogenes that play an integral role in transforming HPV-infected cells into cancerous cells. In March 2011, it initiated a randomized, double-blind Phase II study of VGX-3100 delivered using the CELLECTRA intramuscular electroporation device in women with HPV Type 16 or 18 and diagnosed with, but not yet treated for, cervical intraepithelial neoplasia (CIN) 2/3. The study is designed to enroll 148 subjects. In January 2011, it announced the publication of a scientific paper in the journal Human Vaccines detailing potent immune responses in a preclinical study of its SynCon vaccine for prostate cancer targeting two antigens, prostate specific antigen (PSA) and prostate specific membrane antigen (PSMA).

In January 2011, the Company announced the regulatory approval of a Phase II clinical trial (WIN Trial) to treat leukemia utilizing its new ELGEN 1000 automated vaccine delivery device. The single dose level, Phase II study, called WT1 immunity via DNA fusion gene vaccination in haematological malignancies by intramuscular injection followed by intramuscular electroporation. Cancer Vaccines encodes for hTERT, an antigen related to non-small cell lung, breast and prostate cancers. The vaccine is delivered using its electroporation delivery technology.

Infectious Disease Synthetic Vaccines

In Marc! h 2011, the Company announced the initiation of a follow-on open label, single dose Phase II clinical study in collaboration with ChronTech of the ChronVac-C HCV DNA vaccine delivered using its electroporation technology in treatment naive HCV infected individuals. Its HIV vaccines consist of candidates for HIV prevention, as well as therapy or treatment. PENNVAX-B is designed to target HIV clade B (most commonly found in the United States, North America, Australia and the European Union (EU). PENNVAX-G is designed to target HIV clades A, C and D, which are more commonly found in Asia, Africa, Russia and South America. This Phase I clinical study of PENNVAX-B (HVTN-080) vaccinated 48 healthy, HIV-negative volunteers to assess safety and levels of immune responses generated by Inovio�� PENNVAX-B vaccine delivered with its CELLECTRA electroporation device. PENNVAX-B is a SynCon vaccine that targets HIV gag, pol, and env proteins.

The Company�� VGX-3400X targets H5N1. The vaccine consists of three distinct DNA plasmids coded for a consensus hemagglutinin (HA) antigen derived from different H5N1 virus strains; a consensus neuraminidase (NA) antigen derived from different N1 sequences; and a consensus nucleoprotein (NP) fused to a small portion of the m2 protein (m2E) based on a broader cross-section of influenza viruses in addition to H5N1 and H1N1. Conventional vaccines are strain-specific and have limited ability to protect against genetic shifts in the influenza strains they target. They are therefore modified annually in anticipation of the next flu season�� new strain(s). It is focused on developing DNA-based influenza vaccines able to provide broad protection against known as well as newly emerging, unknown seasonal and pandemic influenza strains.

Animal Health/Veterinary

VGX Animal Health, Inc. (VGX AH), a majority-owned subsidiary, has licensed LifeTide, a plasmid-based growth hormone releasing hormone (GHRH) technology for swine. LifeTide is one of onl! y four DN! A-based treatments approved for use in animals and is the only DNA-based agent delivered using electroporation that has been granted marketing approval (Australia). VGX AH is also developing a GHRH-based treatment for cancer and anemia in dogs and cats. It is developing a synthetic vaccine for foot-and-mouth disease (FMD) administered by its vaccine delivery technology.

Advisors' Opinion:

• [By Sean Williams]

  InterMune (NASDAQ: ITMN  )
  InterMune shares may have exploded higher by 30% over the past week, but there's certain to be a lot of nail-biting on the part of shareholders as we head into earnings season. The reason has been the slow acceptance of the company's idiopathic pulmonary fibrosis drug, Esbriet, based on its pricing in the EU. In previous quarters Esbriet sales have disappointed in a big way, but are expected to rise by 134% to nearly $13 million from last year, though losses are still anticipated to come in at $0.70 per share. Following its recent pop, Esbriet sales had better hit the mark, otherwise InterMune shareholders are probably going to be in for a long day.

  Lunging forward
  Intermune (NASDAQ: ITMN  ) announced second-quarter earnings on Wednesday. Higher-than-expected revenue helped shares advance almost 16% for the week.

  On Thursday, the Securities and Exchange Commission charged a former vice president of finance, accounting officer, and controller of InterMune (NASDAQ: ITMN  ) with insider trading.

• [By Lee Jackson]

  InterMune Inc. (NASDAQ: ITMN) continues to soar on the strength of global sales of its top drug Esbriet. The company is still seeking FDA approval to sell Esbriet in the United States. Before approval can take place, the company is awaiting top-line results from the phase 3 ASCEND study. InterMune expects to release these results during the second quarter of 2014. This could be a huge catalyst. UBS has a $15 price target, which should rise soon, and the consensus is at $16.

  Although its summer, there has been a steady stream of good news about medical marijuana even though important small cap marijuana stocks�Medical Marijuana Inc (OTCMKTS: MJNA) and Cannabis Science Inc (OTCMKTS: CBIS) have been fairly quietly lately while Growlife Inc (OTCBB: PHOT), a more indirect play on the spread of legalized marijuana, has produced�some news for investors:

• [By Bryan Murphy]

  The difference between Growlife's leadership and, say that of competitors like Cannabis Science Inc. (OTCMKTS: CBIS) or Medical Marijuana Inc. (OTCMKTS: MJNA), has been relatively well documented here at the SmallCap Network site. I think the way I - well, someone else - put it back on June 25th says it best...."Growlife is sort of the demure girl in the corner who doesn't do shots off her navel in the bar." It may not have sizzle, but it does have substance.
